Actuators General purpose explosion-proof types NM, ON, NB, NV, NY, ND, WA,
Actuators with two-way coupling, type M, a, B, C, D, e General purpose and explosion-proof, used to complete shut-off of industrial pipeline valves, installed in the premises, under a canopy and in the open air.

Explosion-proof actuators can be installed in hazardous areas of buildings and outdoor units according to the classification of the "Rules for electrical installation (REI) in accordance with the marking of explosion protection motor iexdiibt4 or 2ExdeIICT4.

The actuators are designed for local and remote control valves.

Actuators can be operated in automatic control systems, including the use of microprocessor technology.

The installation position of the actuator is any.

The actuators are designed to operate in intermittent mode activation time (PT) - 25%. The power to the motors is supplied from the AC frequency 50 or 60 Hz, voltage of 220 to 660 C.

The voltage and frequency specified when ordering the drive. In the absence of customer requirements actuators postulate with motor voltage 380 and frequency 50 Hz.

Actuators allow:

the closing and opening of the valve with the remote control by pressing the start buttons and stop the valve in any intermediate position by pressing the "stop";

automatic shut-off motor clutch torque limit when the preset torque on the output shaft in positions "closed","open" or accidental jamming of moving parts in the process for closing and opening;

the alarm on the remote control end position the valve and actuation of the clutch torque limit;

automatic shut-off motor limit switch upon reaching the locking device valve end positions;

local indication of extreme and intermediate positions the valve on the local scale pointer;

remote indication of the degree of opening of the valve on the remote control (in the presence of sensor locations);

automatic switching of the actuator from the position of manual control on electric or independent manual and electric control;

electric lock actuator and the work of other mechanisms and assemblies
